Ambient Light Sensor

The device is sensitive to the visible spectrum.

Ambient light sensor. Ambient light sensor can leak information about user s use patterns and surrounding. Temt6000 is used as ambient light sensor for display back light dimming in mobile phones notebook computers cameras etc. The ambient light sensor is located on the bottom of the computer display panel. An ambient light senor is mounted in an electronic device so that it can detect the light quality and intensity outside.

This avoids having the screen be too bright when the user s pupils are adapted for vision in a dark room or too dim when the device is used. Temt6000 is a silicon npn epitaxial planar photo transistor. The tmd2755 combines a low power vcsel emitter with integrated factory calibrated driver an ir photodetector and ambient light sensor in a narrow footprint and low profile 0 6mm height package. Enable precise light measurements for cost optimized systems using our ambient light sensors.

Each device has a specific operating range of performance from very low light up to bright sunlight. The sensor is made to mimic the function of your eye. So this avoids the screen brightness whenever the users are modified for vision within a dark room otherwise less brightness as the mobile is utilized outdoors during the daytime. Ambient light sensors are typically used to mimic the response of the human eye in some regard or at least be applied to an electronic component that directly relates to the human experience under ambient lighting conditions.

The below circuit and code is for demonstrating basic working of temt6000 ambient light sensor. It perceives that light in the exterior environment and then uses that information to adjust a display such as a computer screen. This information can be used to enhance user profiling and behavioral analysis. The new tmd2755 module s footprint of just 1 1mm x 3 25mm is some 40 smaller than that of the next smallest comparable 3 in 1 ir emitter ir.

The ambient light sensor als products from ams provide measurements of ambient light intensity which match the human eye s response to light under a variety of lighting conditions. Ambient light sensor working principle is it is a photodetector used for detecting the sum of ambient light nearby appropriately reduces the mobile screen s light. The ambient light sensor detects available environmental light and automatically increases or decreases the display backlighting to compensate for low light and high light environments. Two devices can access web sites that include the same third party script that correlates lighting levels over time.
